Swift Http Client Doesn't Send Request - swift

Question

I have this function to test sending HTTP request.
public func test(url: URL) {
print("test")
var request = URLRequest(url: url!)
request.httpMethod = "GET"
let session = URLSession.shared
session.dataTask(with: request) { data, response, err in
print("Entered the completionHandler")
guard err == nil else {
print("error calling GET")
print(err!)
return
}
}.resume()
}
I run the code in my test just to make sure that it's sending request.
And it never gets into the completion block (Entered the completionHandler never got printed). I am new to Swift what do I miss?
func test_download() {
myClient.test(url: URL(string:"https://www.google.com")!)
print("sleeping...")
sleep(10)
print("done...")
}

Answer 1

It seems you're not properly using the closure. Try this instead:
// No need to explicitly set GET method since this is the default one.
let session = URLSession.shared
var request = URLRequest(url: url!)
session.dataTask(with: request) { (data, response, err) in
print("Entered the completionHandler")
guard err == nil else {
print("error calling GET")
return
}
// Do whatever you need to with data and response in here
}.resume()

Looks like you need to configured on your session using URLSessionConfiguration:-
let urlConfig = URLSessionConfiguration.default
urlConfig.timeoutIntervalForRequest = 5
urlConfig.timeoutIntervalForResource = 5
let session = Foundation.URLSession(configuration: urlConfig, delegate: nil, delegateQueue: nil)
//Now try your code
let task = session.dataTask(with: request) { data, response, err in
print("Entered the completionHandler")
guard err == nil else {
print("error calling GET")
print(err!)
return
}
}
task.resume()
